Rick W Posted November 28, 2007 Share Posted November 28, 2007 Having amassed a small collection of Willys engines, apparently post war MB cylinder heads have fins? If so what does a wartime MB head look like in comparison to post war? Also acquired what I believe to be a post war CJ engine, any way of telling what it is? :?

Centurion Posted November 28, 2007 Share Posted November 28, 2007 Hi, could the fins referred to be the ribs on the top of the cylinder head which were introduced into the castings of cylinder heads to stiffen them to prevent warping. I believe that original MB heads or possibly Ford GPW are smooth finished, but Hotchkiss aka Willys Overland France WOF stamped ones do. I dont know if later MB/GPW had these ribs, If that helps, regards Centurion Quote Link to comment Share on other sites More sharing options...
Rick W Posted November 28, 2007 Author Share Posted November 28, 2007 Thanks for that , will post pics of 2 different heads Ive got tomorrow, one has tappet adjustments cast into head, the other not. Neither seems to have strengthening ribs , although I suppose it depends on your definition. Quote Link to comment Share on other sites More sharing options...
Bodger Baz Posted November 28, 2007 Share Posted November 28, 2007 there are loads of cylinder heads for the jeep engines, during ww2 they made several minor changes until very late on they had the strengthening ribs, as usual willys and ford are different! if you have any spare heads without ribs let me know, could do with one ;-) for more info have a look here http://ww2jeeps.com/htm/heads.htm and here http://ww2jeeps.com/htm/Lheadmain.htm and here http://www.g503.com/forums/viewtopic.php?t=106901 Baz Quote Link to comment Share on other sites More sharing options...
